To all whom it may concern:

Beit known that I, FEEDEnmx C. GmLEs `WEBER, of Brooklyn, in the county of 'Kin gs and State of New York, have invented an Improved Machine for Making Wire-Nettings; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use thesame,

. reference being had to the accompanying drawing and letters of reference marked thereon, in

' Figure 1 represents a side elevation of my irnproved machine for'making wire-nettings. Fig. 2 is a plan or top view ofA the same. Fig. 3 is a detail side view of the friction apparatus. Fig. 4 is a detail longitudinal section of the winding- -cylinder. 5 is a transverse section of the same.

Similar letters of reference indicate corresponding parts. v

This invention relates to a new machine for bending wire into a zigzag' form and interlock-- ing successive strands ofthe same, to produce 'a fabric or 4netting of superior or ordinary kind. The invention 'consists principally in the use of astationary cylinder having an internal spiral thread or groove, and in the arrangement therein of arotating at or round rod, which carries the wire around and brings it in contact with the4 spiral surfaces. In, this manner the wire is brought to the desired shape. rllhe invention also consistsin the application to the machine of adjustable frictnlrollersglubricating dev ice, and

guide, all as hereinafter more fully described.

A, in the drawing, represents'the frame or table of my improved netting-machine. It is made of suitable size andshape according to the style of netting to be produced thereon, and preferablymade in sections, which will enable its being taken apart, lengthened, or shortened at will. One section, A', of the table, is setat an angle to the main table A, and contains al series of friction-rollers a a; also the` lubricating-cup b, and the wire-guide c. The main table supports, in a longitudinally-,adjustable or 4entirely stationary block, B, an open-ended hollow cylinder, C, within the inner circumference of which a spiral thread, d, is rigidly fastened,or an equivalent spiral groove provided. D is a dat nod, attached to the end of a short shaft, E, that has its bearings in one end of the frame A, and is, by gearing or otherwise, connected with suitable motive power. The rod D projects lengthwise through. the cylinder 0, as shown, and is revolved there in whenever rotary motion is imparted to the shaft E. The wire to be formed into netting is from a coil drawn between the friction=rollers a a, whichare affixed to laterally-adjustable blocks e e, and set by screws fj', to apply the requisite amount of friction to the wire. From the friction-rollers'the wire passes through the cup b, containing oil or equivalent matter for smooth-l ing the surface ot' the wire. Thence it is by the guide-c'directed to the proper spot where the rod D is to take hold of The end' of the wire is tirst hooked over the rod D, and the latter then revolved so that it will carry the wire around at the same time holding it against the spiral thread orgroove d of the cylinder. On this spi#- ral surface the wire is guided ahead, and receives its convolutions while on the rod D. It is at the same time flattened to finally assume the flat zigzag form represented in Fig. 2. If, in

Aplace of the flat rod D one circular or oval in cross-section is employed, the contolutions of the wire willbe accordingly made round or oval.

The wire issues in the required shape from the end of the cylinder and is deposited on the' taf ble A. When thek desired length which may be suitable has been formed it is cut and moved slightly aside, so that the next course from the cylinder will enter and pass through the meshes of that last finished, and thus complete the netting by interlocking the several strands. -In this manner netting ot' suitable length and width can be rapidly produced at a small expense. Such netting can bensedfor all purposes to which wire-work is now applied, and will, for larger surfaces, being made in large 'sheets or pieccs, be much more acceptable than ordinarywire-netting, s it, has not to be joined in narrow widths. Having thus described my invention, Iclaim as new and desire to secure by Letters Patenti l. The lstationary cylinder C, provided with the spiral groove or thread t1, for the purpose of producing convolutions in wire, substantially as herein shown and described.

2. The rotary rod D, iitted through the staoil-cup b, and guide o, with the stationary cylinder C, spiral thread or groove d, and rotary blade or rod D, substantially as herein shown and described.
